Title in Portuguese
Determinação dos limiares de normalidade dos parâmetros acústicos da voz
Keywords in Portuguese
Análise acústica vocal
voz
Abstract in Portuguese
Existe uma gama de pesquisas destinada à análise digital da voz, cujo intento é o de propiciar ferramentas que possam auxiliar no processo diagnóstico e terapêutico. O intercâmbio entre engenharia e áreas da saúde, como medicina e fonoaudiologia, tem apresentado expansiva importância para um melhor entendimento e aprimoramento de um “saber” mais comum, onde a aplicabilidade de dados quantitativos associados a dados qualitativos acresce conhecimentos nestas duas vertentes. O intuito deste trabalho é o de utilizar dados quantitativos através de uma ferramenta de análise acústica da voz e avaliar sua acuracidade. Para tanto, fez-se exames clínicos e avaliações perceptivas em 130 voluntários. Os resultados obtidos conjuminam com a proposição deste estudo, sendo expressivamente promissores com a exatidão da inter-relação dos achados, com o qual pode-se concluir a veracidade da ferramenta utilizada

Abstract in English
The diagnosis and therapeutic process of the voice has incorporated digital voice analysis as a useful tool for the specialists. The interchange between engineering and health sciences has improved the understanding of this interface area and the association between quantitative data and qualitative evaluation enhanced both. The purpose of this work is to use the acoustical analysis of voice in order to evaluate how accurate is that tool compared with clinical and perceptual diagnostics. A set of 130 subjects was used to evaluate this comparison. The results are consistent and match favorably the clinic and perceptual achievements
